Is porifera diploblastic? I learnt that it has no germ layers.. So hw cm diploblastic or triploblastic ??

Simpler animals, such as sea porifera, have one germ layer and lack true tissue organization. All the more complex animals (from flat worms to humans) are triploblastic with three germ layers (a mesoderm as well as ectoderm and endoderm). The mesoderm allows them to develop true organs while some poriferans may be diploblastic as there always must be an exeption dear Gayathri
